Delivering medicines with microscopic flowers

An interdisciplinary study from the University of Bern reveals that gut bacteria play a crucial role in converting arsenobetaine into toxic arsenic compounds. Results show that arsenobetaine, commonly found in seafood and previously considered harmless, is partly transformed into toxic arsenic compounds by the action of gut bacteria in the mammalian body. These findings raise new questions about the safety of seafood consumption.

For millennia humans have been inspired by the stars but this may soon be a thing of the past due to a significant increase in the numbers of satellites, potentially limiting our view of the night sky. scientists are part of a global initiative to better protect Earth's Dark and Quiet Skies.

Researchers have built a drone that can walk, hop, and jump into flight with the aid of birdlike legs, greatly expanding the range of potential environments accessible to unmanned aerial vehicles.

A new generation of wearable sensors will fundamentally change medicine. Researchers at ETH Zurich have now published an overview showing what is possible with such sensors and what questions their developers should consider to ensure their successful future use.
